Unknown channel balance

Question

I am trying to identify the channel balance shown in the pictures. The length is 27" but there are no markings that I can find on the channel balance. Could you please help me identify the balance?

Thank you for your assistance.

Hello. Based on the nylon attachments, I think this an S395-27. You will need to choose a stamp option, which designates the strength of the balance. Look for a stamp on your old balance that indicates this. If there is none or you are uncertain, weigh the window sash that these balances support. You can then match that exact weight with one of the weight ranges listed alongside each stamp option under the product description of the S395-27 shop page.
